We can control the mechanical properties of our products with tensile strength greater than 200MPa,ring crush strength greater than 350MPa andBrinell hardness less than 260HB especially, to ensure consistently high quality of each individual pipe and fitting.

2) The properties of coating

From a series of chemical analysis and tests, we can control the properties of coating in accordance with EN 877. In addition, we have passed the test on resistance totemperature cycling in Hong Kong. We can also issue the technical certification reports on grey iron tensile,coating thickness and adhesion as our customer's request.
